Application January 31, 1934, Serial No. 209,122 5 Claims. (01. 5351)) to improvements in for metal spring constructions. It

relates particularly to pads adapted to cover and rest on the tops of metal spring constructions such as are employed in inner spring mattress units, spring seats, upholstered furniture and the like.

One of the objects provide a novel pad of will prevent padding materi pad from crowding into or which support the pad, whi

strong, durable, not likely to of our invention is, to the kind. described which al supported by the between the springs ch is simple, cheap, get out of order,

and which will retain its normal form under severe usage and to provide a novel method of reenforcing the pad.

A further object is to provide a novel pad which employs a flexible sheet of fabric which has interlaced with it resilient and means for holding the in its operative position.

The novel features of our reenforcing means, reenforcing means invention are hereinafter fully described and claimed.

In the accompanying drawing illustrative of our invention,

Fig. 1 is a top view, partly broken away, of the preferred form of our improved pad mounted on a coil spring structure, shown in dotted lines.

Fig. 2 is a bottom view Fig. 1.

Fig. 3 is an Fig. 4 is a top view the reenforcing wires Fig. 5 is a plan view cation of our interlacing of what is shown in enlarged section taken on the of our improved for interlacing Fig. 6 is a plan view of still another modification of our means for attaching the wires to the fabric.

Similar characters 'of reference designate similar parts in the different I designates upright spiral by crossed braces 2, and forming views.

springs, connected part of a metal spring structure, such as is used in spring seats, inner spring mattresses and the like.

In the form of our invention shown in Figs. 1

to 3, our improved pad comprises burlap, canvas or similar flexible fabric, such as material, which rests springs upon a sheet 3 of the top'of the coil I, and which supports the usual cotton padding I, and which is reenforced by substantially parallel resilient members, preferably wires 5 of spring steel, spring brass or other suitable material, the wires 5 being,

in this form of our 3. It may also be effected by interweaving of invention, interlaced with the fabric sheet 3 by having the wires 5, which are preferably straight, threaded through the sheet 3.

If desired the wires 5 may be so interlaced with the fabric 3 as to be disposed above the sheet 3 5 at such places, as the wires cross the springs I or the braces 2, thereby avoiding contacting of the wires with the springs or braces.

To hold the wires 5 from substantial longitudinal movement relatively to each other, suitable anchoring means may be employed. For anchoring the wires 5, each of the latter has at one end an eye 6, said eyes being alined and having extended through them a relatively stiff member, such as a resilient wire 1, the ends of which are respectively fastened to the outer eyes 6.

By anchoring the wires 5 only at one set of ends, and by employing straight wires, the sheet 3 is free to slip on the wires upon unequal depression of the springs I, thus reducing wear on the sheet.

8 designates the usual covering for the cotton padding 4, which, with the fabric sheet'3, is held by our reenforcing wires 5 from crowding into or between the cc of the springs I.

The interlacing of the resilient members, such as the wires 5, with the flexible fabric, may be effected, as has been described, by threading the membersv back and forth through the sheet the resilient members and the fabric in the making of the sheet 3. Or the interlacing of the members 5 with the fabric sheet 3 by stitching 9 passing across the members 5 and through the sheet 3, as shown in Fig. 4. Or the interlac- 35 ing may be effected by passing strands III in zig zag fashion over and under the members 5 and through the sheet 3, as shown in Fig. 5. Or the interlacing may be effected by looping strands I I around each member 5 and through the sheet 3, as shown in Fig. 6.

The members 5 may be extended horizontally in any direction with respect to the sheet 3 or to each other, as shown in the drawing they are shown disposed parallel 'th each other and lengthwise of the sheet 3.

Other modifications of our invention, within the scope of the appended claims, may be made without departing from the spirit of our invention.

What we claim is:-- 1. In a pad of the kind described comprising an upper cloth sheet and a lower cloth sheet and padding between said sheets, straight parallel resilient wires threaded back and forth through and slidable in said lower sheet and having one set of ends free, and means engaging the other set of ends of said wires and disposed above said lower sheet for holding said wires from substantial longitudinal movement relatively to each other.

2. In a pad of the kind described comprising an upper cloth sheet and a lower cloth sheet and padding between said sheets, straight parallel resilient wires threaded back and forth through and slidable in said lower sheet and having one set of ends free, the other ends of said wires above said lower sheet being respectively provided with eyes, and a member extending through said eyes and holding said wires from substantial longitudinal movement relatively to each other.

3. In a structure of the kind described, the combination with a metal spring structure, and a 'pad comprising a cloth sheet disposed on said spring structure, an upper cloth sheet and padding between said sheets, of straight parallel resilient wires threaded back and forth through and slidable in the first named sheet, the latter being between said spring structure and said wires where said wires pass directly over parts of said spring structure, said wires having one set of ends free and eyes at their other ends, disposed above the first named sheet, and a member extending through said eyes and holding said wires from substantial longitudinal movement relatively to each other. a

4. A pad of the kind described comprising an upper cloth sheet and a lower cloth sheet and padding between said sheets, wires threaded back and forth through and slidable in said lower sheet and having one set of ends free, and means engaging the other set of ends of said wires for holding them from substantial longitudinal movement relatively to each other.-

5. In a structure of the kind described, the combination with a coil spring structure, and a pad comprising a cloth sheet disposed on said spring structure, an upper cloth sheet, and padding between said sheets, of wires threaded back and forth through and slidable in the first named sheet, the latter being interposed between said spring structure and said wires where said wires pass directly over the coils 'of said structure, said wires having one set of ends free, and means engaging the other set of ends of said wires for holding them from substantial longitudinal movement relatively to each other.
